Manhart Làm thế nào để xác nhận độ chính xác của máy uốn CNC servo điện dầu?

The accuracy confirmation of oil electric servo CNC bending machines usually involves multiple aspects. The following will be summarized in a clear point by point manner by combining relevant numbers and information in reference articles:
1. * * Straightness of bent workpieces * *: For workpieces with a length of 5.9 meters, the straightness error should be within 15 ‘(minute angle).
2. * * Repeated positioning accuracy of bent workpieces * *: It should reach a range of 3-5 threads (i.e. 0.03-0.05mm) to ensure the repeated machining accuracy of the workpiece.
3. The forming accuracy of the bending workpiece should be within 18 threads (0.18mm), which is an important standard for measuring the forming effect.
4. * * Gear Finger Accuracy * *: The error of moving from left to right should be within 10 threads (0.1mm) to ensure the accuracy of the gear finger.
5. * * Dynamic performance * *: The action should be gentle and there should be no shaking throughout the entire process to ensure the stability of the processing.
6. * * Functional performance * *: including graphic programming, Chinese storage, controllable jog, convenient shaping, sensitive yielding, curve debugging, etc., ensuring the convenience and efficiency of operation.
7. * * Stability * *: All CNC fixtures of the electro-hydraulic machine should be able to ensure the convenience of switching and bending long and short parts and the standardization of angles when in mechanical 0 position.
8. * * Positioning accuracy * *: The maximum positioning accuracy can reach 0.01MM, supporting two decimal places to ensure high-precision machining.
9. * * Servo motor accuracy * *: Servo motors using bus servo methods, such as Delta servo motors, can achieve an accuracy of 0.001mm, ensuring the accuracy of servo motor positioning.
10. * * Workbench and slider vertical plate processing accuracy * *: All workbenches and slider vertical plates adopt mirror processing to ensure vertical accuracy and bright processing surface.
11. * * Assembly accuracy * *: Assembled by experienced installers, each machine should be calibrated at least 5 times to ensure high standards for each electro-hydraulic machine.
12. * * CNC Quick Clamp and Mold Precision * *: Select a good CNC quick clamp, and ensure that the error of each quick clamp is within 0.02MM; The mold is made of imported materials, ensuring a docking accuracy of within 0.02MM.
In order to confirm the accuracy of the oil electric servo CNC bending machine, it is usually necessary to refer to the above standards and conduct a comprehensive evaluation based on actual processing effects and measurement data. In addition, regular calibration and maintenance are also key to ensuring the long-term stable operation and accuracy maintenance of CNC bending machines.
